Like you said it all depends on a lot of different things. What kind they are, how old they are, are they laying and all that. Most of the time I sell my baby muscovies at 5 dollars. My mixes are only 3 dollars. If I wait till they are 6 months old they are between 8-10 a peice for both the mixes and the muscovies. And then if I wait till they are a year old (which I have only done once) i sold my trio(muscovies) for 45 dollars. So $15 a duck. I hope this helps a little. Im not sure how hard it is to sell them where you live but I know here in Missouri its not to terribly hard.
